It's believed to have started in a first-floor sitting room. Firefighters said the fire, which was reported near South 27th and D streets around 7:50 p.m., produced a tremendous amount of thick, black smoke.

The house is located near Highland Park.

The teenager was transported in serious condition to the University of Nebraska Medical Center for smoke inhalation. The teen was one of eight people who live in the residence, according to firefighters on the scene.

The Salvation Army was on the scene so those affected by the fire have a place to stay for the night.
